The difference and advantages of galvanizing and hot-dip galvanizing

Hot dip galvanizing is dipped in zinc solution melted by heating, with fast production speed and thick but uneven coating. The minimum thickness allowed by the market is 45 microns, and the maximum can reach more than 300 microns. The color is dark, the consumption of zinc metal is much, and the matrix metal forms the infiltration layer, the corrosion resistance is good, and the outdoor environment can be kept for decades.

Cold galvanizing (galvanizing) is in the electroplating tank through the current unidirectional to gradually plating zinc on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. The relative

Hot dip galvanizing, electric galvanizing production cost is lower.

The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is bright silver white with yellow. Hot dip galvanizing shiny white.
